The most ripped off heavy metal riff

Riot - Swords and Tequila Accept - Flash Rockin’ Man Iron Maiden - 2 Minutes to Midnight Mercyful Fate - Curse of the Pharoahs Raven - Seek And Destroy Some think Venom’s Welcome to Hell sounds very similar, but I don’t. That’s why the songs is not included in the video. If you know of any other songs that sounds similar, please let me know!
